The Rare Fruit of the Kazook Tree is a rare, and expensive, yet small fruit only seen in the episode "Le Big Switch."
The fruit has a strong rancid smell (and probably a foul taste as well), yet is still expensive as it costs $52, and it needs shredded gold (literally) as an ingredient to neutralize its awful smell. It does not look like a traditional fruit, rather a small flat cylinder made up of some beans, rice or some other sort of grain. It has one small leaf sticking up out of it. It is unknown if it is part of the fruit, or if it is put there simply for decoration.
- The Rare Fruit of the Kazook Tree is based on the real-life Durian fruit, which has a smell that is said to resemble rotten eggs and gym socks.
